METALLIC FINISHING-PLATE.

SPECIFICATION forming part of Letters Patent No. 496,478, dated May 2, 1893.

Application filed January 31, 1893. Serial No. 460,395- (No model.)

To all whom it may concern:

Beit known that we, WILLIAM S. GRAFTON,

residing at Steubenville, in the county of Jefferson and State of Ohio, and EDWIN O. 5 EWING and ALEXANDER GLAss, residing at Wheeling, in the county of Ohio and State of West Virginia, citizens of the United States, have invented certain new and useful Improvements in Metallic Finishing-Plates, of which the following is a specification.

Our invention more especially relates to the manufacture of metal plates for use in covering ceilings, walls, 850.

The object of our invention is to so form the plates that they may be readily joined together in such manner as to provide concealed joints, thereby producing a continuous effect,

joint strips, supplemental rosettes, &c., which 1 artificial rosettes b, having raised edges b, and concave or sunken middle portions b within each of which is a'knob or projection, Th of the size and form of a nail head.

produce a panel effect, being discarded.

Our object also is to so form the plates that their decoration may be facilitated and a plurality of designs produced. Accordingly,

we make the plates of uniform size, and stamp them with'syinmetrical figures, by producing z 5 depressions on one side and corresponding ridges on the other, and at each edge of the plates, we provide a hollow ridge adapted to overlap a corresponding ridge on another plate. The depressions and ridges in the body of a plate are also adapted to match corresponding ridges and depressions in the body of other overlapping or partially overlapping plates. The hollow ridges on all the plates are similar in form so that there is no diffi- 5 culty in matching, and when the plates are applied to the wall or ceiling, the joint is scarcely perceptible. Each plate is divided by the ridges into squares of say six inches on a side, and each of these squares may be 40 further ornamented, as by employing ridges crossing at the center of the square and connecting the diagonally opposite angles thereof, or by employing four arcs connecting the four angles of the square. The ridges form- 4 5 ingsub-divisions cross each other, and at each joint or point of intersection, we form an artificial rosette, within which is a small knob or button, of the size and appearance of a nail head.

' plate. The diagonally opposite parts 1 and 3,

In the accompanying drawings illustrating our invention-Figure 1 is a view of one of our improved plates joined to sections or parts of adjacent plates. Fig. 2 is a detail view, in section, on the line 2-2 of Fig. 1. Fig. 3 isa detail view in section on the line 33 of Fig. 1. Fig. Ais a detail view in section on the line 44 of Fig. 1. Fig. 5 is a perspective view of the corner. of two adjacent plates.- Figs. 6 and 7 are diagrams, showing several of our plates joined together and variously decorated.

We preferably form the plates of sheet steel, and make them square in outline, and subdivide them into squares A, of equal size, by hollow ribs or corrugations a, and correspond ing intersecting ribs or corrugations a. At the intersection of the ribs a and a, we form Each plate, as shown in Fig. 1, is divided into four principal parts, 1, 2, 3, 4:, each of which is one-fourth the area of the entire are similarly ornamented, and the parts 2 and 4 have similar ornamentation, but differing from that of the plates 1 and 3.

The entire plate is sub-divided into four equal subdivisions A, by the ribs or ridges a a, and each sub-division of the parts 1 and 3 is provided with ribs or ridges c, which cross each other at the center of the sub-division, and connect the opposite angles thereof. Each sub-division of the parts 2 and 4 is pro vided with arc-shaped ribs or ridges 01, connecting the angles of the sub-divisions and having the same length and radius. By this method of ornamenting the plates, we provide means for varying the decoration of the continuous ceiling, wall or surface.

It will be found, by reference to Figs. 6 and 7, that the surface is made up entirely of plates such as illustrated in Fig. 1, and that various designs are produced by differently coloring or decorating the symmetrical figures formed by the ribs or ridges in the plates.

A variety of designs, (not illustrated) may be produced from the same plates, or plates similarly formed by joining them in different ways and by varyingthe decoration,the ridges forming the boundaries or guides in each instance, and thus very materially facilitate the process of ornamentation.

Instead of concealing the joints in Figs. 6 and 7, we have shown the plates slightly separated, so as to clearly indicate the form of each plate, and show where it joins its fellow.

Referring again to Figs. 1 to 4, it will be observed that the edges of the plates overlap each other. The edges of all the plates are formed in precisely the same way, being bounded by the hollow ribs or ridges and the artificial rosettes which are located at equal distances apart in all the plates are also hol low and adapted to fit over the corresponding projecting parts in adjacent plates. The depressions and ridges in the body of a plate are also adapted to match corresponding ridges and depressions in the body of other overlapping or partially overlapping plates.

The nails 0, for securing the plates, should be driven through the knobs b It is not necessary, however, that nails should be driven at all the knobs, and where the nails are omitted, the knobs being similar in form to nail heads, give to the surface a uniform appearance.

\Ve claim as our invention- 1. A metallic finishing plate formed substantially as hereinbefore described with hollow ridges and with artificial rosettes at the intersection of the ridges, both the ridges and rosettes being hollow, as set forth.

2. A metallic finishing plate, formed substantially as hereinbefore described, with hollow ridges at its edges, and with artificial rosettes at the intersection of the ridges and having also hollow ribs or ridges dividingthe plate into squares of equal area, said ridges being provided with hollow artificial rosettes at the intersection of said ribs or ridges.

8. The square or rectangular metallic finishing plate hereinbefore described, sub-divided into squares of equal area by hollow ribs or ridges and having artificial rosettes at the intersection of the ridges, the ribs or ridges and rosettes being hollow and adapted to overlap corresponding ribs and rosettes on adjacent plates.

4:. The metallic finishing plate herein described comprising four principal parts, 1, 2, 3, 4:, of equal area, the diagonally opposite parts or squares 1 and 3 having hollow ribs or ridges similar in form, while the diagonally opposite parts 2 and t have ribs or ridges similar to each other but differing from those of the parts 1 and 3.

5. The herein described metallic finishing plate divided into four parts 1, 2, 3,4, of equal area, each part being further divided into sub-divisions A, by ribs or ridges a, a, each sub-division of the parts 1 and 3 having its opposite angles connected by crossed ribs or ridges, while each sub-division of the parts 2 and 4 has its angles connected by four arcs of equal length and radius, the organization being such that various symmetrical figures are formed in the surface produced by joining a plurality of plates and the decoration of the plates is facilitated.

Intestimony whereof we have hereunto subscribed our names.
